Specification of Letters Patent. Application filed February 4, 1909. Serial No. 16,004.

Patented Aug. 3, 1909.

To all whom it wiay concern:

Be it known that we, LnoN DESVAUX and HENRI ALLAIRE, citizens ofthe Republic of France, residin at 32 Rue Saint-Lambert,

and 13 Rue de la Comete, Paris, France, respectively, have invented new and useful Improvements in Improved Plastic. Products,

of which the following is a specification. 4

The present invention has for its object a new plastic product for the manufacture of combs, molded objects of any kind and other applications.

The invention consists in the a plication to the manufacture of plastic pro ucts, and particularly to products of which celluloid 'IS the base, of a material extracted from maize, and which has, up to the present,

- been utilized only as a food product.

-under the name of maizine.

In the application to celluloid the elements which constitute the substance known as celluloid, that is to say nitrocellulose and camphor or any suitable substitute for the latter material, are added in varying proportion to a particular albuminoid which is extracted from maize and which has the property of dissolving in the ordinary solvents of the said elements. Y

None of the albuminous substances hither- 'to employed in addition to the celluloid or able to-pure celluloid, by reason of lack of solubility in the solvents of one or other of the principal constituent elements of the product.

treatin maize with higher alcohols such as amyl a cohol and is known as a food product It forms the subject of Patent No. 744510 granted to Donard and Labb.

Fork the manufacture of the new plastic p'oducts, the maizine may advantageously :employed as follows :-To-a mixture of nitrocellulose and camphor dissolved in alcohol in proportions which may be greatly varied, for example, three parts by weight vofnitrocellulose and one part byweight of camphor, are added,f or example three parts by weight of nnuzine previously mois- Witnesses i tened with alcohol. The compound mixed by stirring, and then worked up by the ordi-.

quality of the product, for the reason, al

ready given, that it is soluble in the solvents of both the elements, and forms no precip1- tate in the en ire mass. The final product is erfectly homogeneous and transluci'd, is far ess combustible than celluloid, and the net cost is much lower. 4

The product can of course be colored by the ordlnary means; and subse uently inert bodies may be added thereto. oreover the proportions of the nitrocellulose, camphor or the substitute for camphor and of the maizine may be varied at will according to the particular use for which the product is desi ed.

e claim: a

1. As a new article of manufacture, a plas tic product such as herein described consisting of celluloid and an albuminoid product tic product consisting of nitrocellulose, camphor or its substitutes, and maizine, the latter being an albuminoid product extracted from maize and soluble in the solvents of both nitrocellulose and camphor or its substitutes I 3. As a new article of manufacture, a plaswei t of nitrocellulose, one part by weight of camphor and three parts by welght of maizine previousl moistened with alcohol.

In testimony whereof we have signed our names to this specification-in the presence 0 two subscribing witnesses. l
